I really haven't had much trouble uploading pics on this forum using javauploader but have on another forum. I downloaded a program (free) called FastStone Photoresizer. I'm sure there are more but this is the one that came up when I googled it.
It makes it extremely easy to resize photo's, whether one or a hundred it is very fast. There is also a cool renaming option that I have used a couple times, you can take as many pics as you want and rename them in order, for instance I went on a motorcycle trip and renamed all my pics "Bike Trip###" so all my trip photos were in order and had the words "bike trip" in the name.
Anyways just thought I would post this here because it was useful for me, someone else may like it as well.
